My invention comprises a simple and effective locking means adapted to an autostrop razor known on the commercial market as Valet and shown, more particularly, in

Letters Patent No. 1,022,726 dated April 9, 1912, being a type of safety razor in which the blade is pivoted so-as to swing freely during the act of stropping the same'but which, when in use for the shaving opera 1 tion,

frame constituting the guard which has heretofore been manually held upon the razor blade during the shaving act. v

By my improvements, this guard member is locked relatively to the main frameto which the blade is pivoted so that when the guard is properly positioned over the cutting edge of the blade, said guard may be rigidly held mechanically to prevent accidental release of the pivoted blade, thus preventing possible serious injury to the user.

More particularly, the blade is carried by a pivoted member in a head adjustably secured to the end of the handle and the guard is pivoted to the adjustable head on a transverse axis parallel to the axis of the pivoted blade carrying part, and these features, common in this type of razor, are further distinguished by providing the handle with a notch or groove and the guard with a lug or projection which snaps into the notch or groove of the handle to form a detachable locking connection which may be readily moved to release the guard and blade when 5 necessary for the stropping operation, but.

otherwise holds said guard as a protection to the cutting edge of the blade during the act of shaving.

My invention further comprises details of is held against swinging by a plvoted upwardly projecting part 16 adapted to snap into "of the ting edge of the blade construction which, together with the feairelease the blade to tures above mentioned, are more fully de-- tional view corresponding to a portion of Fig. 2.

2 is. the handle and is-provided with a threaded end 3 which sorews into the head frame 4, said head frame having forwardf pro ecting flanges 5 between which are provided rotary shafts Grand 7 geared together atone end by pinions 8, .The shaft 6 is provided with a downwardly extending socket portion '9 which is adapted to receive 'the blade 10 to so hold it that, the cutting edgel-l thereof may swing freely with respect to the strop' during the stropping operation The blade is de tachably connected with thesocket portion 9, as is customaryin a razor of this 1 character.

" 12 is a pivoted comb-like guard having its "lateral edges 13 bent to from socketsto engage the extreme ends of the cutting edgeof theblade and to properly hold the blade in respect to the guardduring the shaving operation. This pivoted guard 12 ishingedat 14 to side lugs 15 on the head frame 4:. Fur- 'thermore, the guard 12 is provided with an wardly extending arn1 16 bywhich it can be oscillated about its pivot points 14. This is provided with an opening 17 through which the shank of the handle 2 extends. I This handle shank is provided with an annular groove 18 and the upwardly projecting part 16 of the guard 12 is provided witha downwardlyengaging edge 19 fwhich is the annular groove 18 handle shank, as is clearly shownin Fig. 2. In this manner, the guard is detachably lockedin engaging position with the cutandwill hold this en" gagernent during the shaving operation. To

ping purposes, forward upon the projecting-part 16,-with'the result that'its'engaging part 19' is disengagedallow 1t to swing forstop 4 t s only necessary to press from the groove18 and in turn causeslthe en- I gaging parts 13 torelease the lowenend 11 of the blade. p

The'annular groove 18 insures proper engagement .with the part 19 for any circumferential adjustment of the handle, but broadly considered, it is not necessary that thenotch or groove 18 shall extend co npletely around theshank of thedhandle, since it-ma-y be i I Havingthusfgdescribed my inventionjwhat i V 7v zanddesire to secure by Letters'Pat- 'InentjWith theblade during the shaving opershaped in any manner so long as the part 19 isadaptedt'o make a locking connection with thefhandle.
